Temperature controller: can control the temperature between two temperatures. For example, the temperature is controlled between 98-100 degrees, when the temperature is lower than 98 degrees, the appliance or equipment is heated, so that its temperature rises; When the temperature is above 100 degrees, the appliance or equipment stops heating or cooling, causing its temperature to drop.

Specific applications such as: high and low temperature box.

Temperature limiter: Limits the temperature below a certain temperature. For example, the temperature is limited to 101 degrees, when the temperature is higher than 101 degrees, the appliance or equipment will stop heating or cooling, so that its temperature will drop.

Specific applications such as: high temperature box.

The same can be said of thermostats and temperature limiters.

From the frequency of use to understand, for example: an electric iron has a temperature controller and a temperature limiter.

The thermostat is the adjusted part with bimetal pieces, he is mainly to let the temperature of the iron to reach a relatively constant state, the frequency of use is very high, and the temperature limit is a temperature fuse connected with him, is in the abnormal situation can stop the equipment will not be dangerous. The frequency of use is very low.
